Hi,
1. I am confused about SIP/MGCP located on which layer.
some source said It is located on layer 7, some says on layer 5 (session layer).
2. Do we use OSI model for Voip or TCP/IP or doesn't matter ?
Is the OSI model only logical or It "really exist" ?
3. Serial interface is located at which interface ?
When I studied CVOICE, It covered about configuring ISDN :
isdn switch-type primary-qsig
controller t1 0/0
pri-group timeslots 1-23
interface serial 0/0:23
isdn incoming-voice voice
Could you tell me on which layer those command are located ?
Is it on Layer 1 ?
4. When I learned CVOICE. It also mention about VoFR (Voice over Frame Relay)
What's the difference between VoFR and Voip ?
VoFR means Voice over Frame relay or Voice over IP over Frame Relay ?
I only know that Frame relay is on Layer 2 and IP is on Layer 3
Please solve the puzzle..
Thank You very Much
